I believe that as we allow ourselves to gravitate, with loving curiosity, toward that which most interests us, we quite naturally come upon it. Trust yourself as you tune inward and then redirect yourself outward to find the reading resources that resonate most with you, moment by moment.
I recommend anything and everything by my mentor and teacher, Abraham Hicks.
In particular, I highly recommend The Amazing Power of Deliberate Intent.
Another important book is Metaphysics 101: Manifesting Your Dreams by Calvin Lehew.
Additionally, I recommend the timeless book, The Ever-Loving Essence of You, written by myself and Lauren Targ.
